Well, I usually intend to speak up at least once during a class period. I'll comment if I truly think that my contribution is worthwhile. I do make an effort to participate, but I hate to add further superfluous posturing. I do not mind openly disagreeing with other students, but I'm not interested in engaging in a lengthy debate. I had a few 'debates' with professors as an undergrad, but these were few and far between. I'm very non-confrontational in general, but I can be a bit blunt, therefore I'm usually considerate of my cohort's feelings.
My question is: Do professors ever look down upon more reticent students?
